The ability of the JONSWAP model to describe swell spectra is analysed and the quality of the fit of this model is compared with the fits produced by a Gaussian model. The study is based on directional wave spectra from measurements made at the Maui location situated in the west coast of New Zealand and at the Bonga location situated near the coast of Africa. The analysis is performed for single peak swell sea states and for the swell component of two peaked spectra.The comparison of the spectral parameters and the fit of the models with the measured narrow swell spectra, suggest that the JONSWAP model describes better the swell spectrum than the Gaussian model, in particular in the high frequency range.

Abstract

The ability of the JONSWAP model to describe swell spectra is analysed and the quality of the fit of this model is compared with the fits produced by a Gaussian model. The study is based on directional wave spectra from measurements made at the Maui location situated in the west coast of New Zealand and at the Bonga location situated near the coast of Africa. The analysis is performed for single peak swell sea states and for the swell component of two peaked spectra.The comparison of the spectral parameters and the fit of the models with the measured narrow swell spectra, suggest that the JONSWAP model describes better the swell spectrum than the Gaussian model, in particular in the high frequency range.
